aluminum atoms to equal the thickness of a sheet of aluminum foil

true metals. Complete Periodic Table of Elements Warm-up

Elements are organized in the periodic table in such a way that
there are patterns of elements placed close together that have
similar properties. For example, knowing the properties of one
element in a column of the periodic table will help a person
predict the properties of other elements in that same column.

the periodic table. Describe two properties common to elements
found at the far right of the periodic table. Complete Periodic
Table of Elements Warm-up worksheet

On the far left side of the periodic table the elements are all
metals. So, they are solids at room temperature and are good

change of sub-atomic particles. For example, a neutron can change
